Kubernetes Cluster Setup

Kubernetes cluster using Ansible and Vagrant

Requirements

You'll need the following installed on your workstation

1. Ansible
2. Vagrant
3. Virtualbox
4. Kubectl

Usage

1. git clone https://github.com/Ammly/k8s-cluster.git
2. cd k8s-cluster
3. vagrant up

This will set up the following

• A master node called k8s-master
• 2 worker nodes k8s-worker-1 and k8s-worker-2

Accessing master

vagrant ssh k8s-master

Accessing nodes

 vagrant ssh k8s-worker-1
 vagrant ssh k8s-worker-2

To access your cluster from your host, run the following command to copy kube config from k8s-master to your home dir

scp vagrant@k8s-master.test:/etc/kubernetes/admin.conf ~/.kube/config

Alternatively you can install vagrant scp plugin and run the following

vagrant scp k8s-master:/etc/kubernetes/admin.conf ~/.kube/config

Create .kube/ directory if it doesn't exist

kubectl cluster-info

Get nodes in your cluster

kubectl get nodes
